To aZZwlwm it may concern:

Be it known that 1, JOHN H. CBOWELL, a citizen of the United States,residing at Vineyard Haven, in the county of Dukes and State ofMassachusetts, have invented a new and useful Press, of which thefollow- 1 ing is a specification. v

This application is a division of my a plication Serial Number 687,206,filed ll l rch 29, 1912, on which Letters Patent No. 1,076,023 wereissued October 21, 1913.

The purpose of my invention is to provide a press usable as a combinedfoot and screw press.

To these ends my invention consists in the new andnovel construction,combination and arrangement of parts hereinafter described, ingdrawings, in Which,

Figure l is a front elevation of a press embodying my invention. Fig. 2is a side elevation of the same, partly in section.

Like reference letters and numerals indicai'e like parts where theyoccur in the drawin S- s l .%eferring to the drawings, A represents theframe,'compr1s1ng ugright members, as

A and a cross member 2 connecting them at their upper ends. These partsare pref erably integral, and are mounted upon a table A, in turnsupported on legs or stand ards, as A Said uprights are fitted to serveas guideways in which a follower l is fitted for reciprocal verticalmovement; as actuated as hereinafter described. Said follower isprovided with a transverse mediately disposed perforation into which extends the prolonged upper end or arm 2 of the treadle 2 pivotallymounted upon and between said uprights, and below said cross member.Said cross member is provided with a centrally disposed perforation,internally threaded, for the operation therethrough of an externallythreaded screw 3, carrying upon its upper end an operating handle 4 inturn carrying a counterweight 4. To the lower end of said screw 1 securethe follower 1. A collar and set screw 3 adjustably limit, in the welllmown-way, the

11d illustrated in the accompany- I downward movement of the screw 3,and the follower 1.

By reason of the construction, combination' and arrangement of theparts, as shown and described, I am enabled to use the press to obtainthe benefit and advantage of a combined screw and foot press, For itwill be noted that whether the press is operated by the handle or by thetreadle all the parts will act and move unitedly, and the counterweight4: will be caused. to swing upon the screw 3 as a pivot within apredetermined arc with velocity dependent upon the speed with whicheither the handle or treadle are operated, and that its impetus will besuddenly checked at the end of such movement and thereby materially andimportantly add to the force and effectiveness of the blow of thefollower-carried die upon the piece of work disposed upon the table A inthe path. of the follower. I am thus enabled toutilize to the fullestextent the benefit and advantage of the impetus and weight of thecombined counterweight, follower and treadle to make more efiective theoperation of my press. This is a novel, important and very useful andadvantageous feature of my invention. 1.

I claim:

1. In a press the combination with uprights provided with guideways andwith a cross member connecting 'said uprights and provided with aninternally threaded perforation, of a follower slidably fitted in said'guideways and provided with a transverse mediate perforation, anexternally threaded screw arranged for operation throu h said threadedperforation, and operative y connected to said follower, acounterweighted arm carried on the opposite end of said screw andrevolubly therewith, and a pendent pivotally mounted treadle operativelyconnected with said follower and arranged and adapted to operate inconjunction with said screw to actuate said follower.

2. In a press, the' combination of a screw operated followerfor thepunch, the operating' screw, the die, the counterweighted arm carried onsaid screw, with a pendent pivotally mounted treadle operativelyconnected connected with said plunger, and a pivotally with thefollower, and arranged and adaptmounted foot trcadle operativelyconnected ed to operate in conjunction with the with said plunger.
